I’ve never fit in with my age group growing up. I’m both mature and immature at the same time. For example, as a teen I loved old music (classical and 60s pop) , never went clubbing or to parties, and dressed and behaved like an adult.
I'm 37 now, and I still like watching cartoons, love playing video games, and I love toys. I can get along very well with young children and play well with them. Like a child, I’m perfectly happy just to stop and stare at insects in a park, poke them with a twig, see what happens.
I’m terrible with money, don’t have a stock portfolio like my NT peers, and generally am not interested in their adult pursuits like wine, golf, sport or current events. I still feel like a kid but all this immaturity is hidden. On the outside I just seem like a very serious and private person. Only my immediate family sees the immature side of me.
